Salivary concentrations of Streptococcus mutans and Lactobacilli during an orthodontic treatment. An observational study comparing fixed and removable orthodontic appliances

Clinical and Experimental Dental Research, 2019
This study aimed to investigate salivary concentrations of Streptococcus mutans (S. mutans) and some Lactobacilli, and plaque index (PI) in patients wearing fixed versus removable orthodontic appliances.

A dendrimer enhanced CRISPR/Cas12a performance for the evaluation of acidogenic capacity in cariogenic bacteria

Interdisciplinary Medicine, EarlyView.
A CRISPR/Cas12a‐powered dendritic DNA nanostructure is assembled to create confined enzymatic microdomains, enabling ultrasensitive detection. Integrated into a paper‐based origami biosensor, it allows equipment‐free on‐site quantification of acidogenic pathogens for the early diagnosis of dental caries.

Ordered assembly of Cas12a for better performance of CRISPR/Cas system with application to the diagnosis of dental caries

Interdisciplinary Medicine, EarlyView.
Here, we present a tetrahedral DNA framework (TDF)‐mediated Cas12a ordered assembly strategy. TDFs arrange CRISPR/Cas12a into ordered structures controllably, enhancing catalytic efficiency through localized Cas12a hotspots while maintaining spatial intervals to facilitate substrate diffusion.

Effects of resveratrol on cariogenic virulence properties of Streptococcus mutans

BMC Microbiology, 2019
Streptococcus mutans is the principal etiological agent of human dental caries. The major virulence factors of S. mutans are acid production, acid tolerance, extracellular polysaccharide (EPS) synthesis and biofilm formation.

Transient gingival inflammation is associated with epithelial dysfunction and systemic immune activation beyond clinical improvement

Journal of Periodontology, EarlyView.
Abstract Background The oral cavity significantly influences systemic health. Gingivitis, an early reversible stage of periodontal disease, may trigger systemic immune changes by facilitating bacterial translocation. This study examined the immune responses elicited by experimental gingivitis and their systemic immune impact, specifically in relation ...

Investigation of Antibacterial Effect of Cuminum cyminum and Cuminum cyminum against Streptococcus mutans and Streptococcus pyogenes

Novelty in Biomedicine, 2019
Background: Streptococcus mutans is major cause of tooth decay. In addition, there is some report about effects of Streptococcus pyogenes on odontogenic infections. Herbal drugs is now administrating for treatment of some disease.

Effect of D-cysteine on dual-species biofilms of Streptococcus mutans and Streptococcus sanguinis

Scientific Reports, 2019
Dental caries is a highly prevalent disease worldwide. It is caused by the cariogenic biofilms composed of multiple dynamic bacteria on dental surface.

Aging and periodontitis increase brain dissemination of oral bacteria

Journal of Periodontology, EarlyView.
Abstract Background The microbiome is a dynamic system that changes throughout life. Studies have revealed the relationship between periodontal disease and the oral microbiota; however, the impact of periodontal disease on the expression of senescence markers and on the inflammaging of the oral and systemic microbiome remains unclear.

Cefdinir reprograms Gram‐positive bacteria to synergize with lysozyme against superbugs

mLife, EarlyView.
Abstract Multidrug‐resistant (MDR) bacteria pose a critical global health threat, urgently requiring solutions. Cefdinir, the highest‐selling third‐generation cephalosporin but one now facing clinical obsolescence due to escalating resistance, is conventionally classified as a nascent cell wall synthesis inhibitor.
